The problem is: there is only 1 Dusk Stone available in-game currently -- the same for Shiny Stone and Dawn Stone (but the last one is not urgent for now). Hmm... Well, while time consuming, someone could make an alt account and go gather a new stone. Or find someone who hasn't used theirs.

Now for an unrelated and off-topic suggestion: Maybe this wikia could benifit from a "Trading" forum section...
